Vengeful (Villains Series, Book 2)

Sydney Clarke once had Serena―beloved sister, betrayed enemy, powerful ally. But now she's alone, except for her thrice-dead dog, Dol. And then there's Victor, who thinks Sydney doesn't know about his most recent act of vengeance. Victor himself is under the radar these days―being buried and re-animated can strike concern even if one has superhuman powers. And Eli Ever still has yet to pay for the evil he has done.
